It means that for a 50 meter + cap radius, two people are the minimum needed to cap. 4 and 6 are respective to 100m+ and 150m+. At least that what is what I got out of it.

If that's the case then it sounds like a good addition. Although im not sure ther was a problem with this i havent read any complaints. Sometimes i think the game gets fiddled with too much. Also are the RPG stats being reverted?
